` PORT LIGHT.

Application filed January 6, 1922, Serial No. 527,376. Renewed June 5,1925.

To all whom it may. concern.'

Be itknown that'I, HARRY B. HILLS, a citizen of the United States,vresiding at Hudson, in the Ycounty of Columbia and claims. v A

In the acompanyingdrawings, Fig. l is a front elevation of a port lightembodying my invention. Fig. 2 is a 'cross-sectional view, the sectionbeing taken on the line 2-2 of Fig. l. Fig. 3 is a detail view of thehinge connection between the light and supporting frame. Fig. 4 is adetail view y y of a means for lifting the cover from its seat.

Similar letters of reference designate corresponding parts in all of thefigures. y

A designates an annular rin which isl y suitably secured by bolts 'orrivets in an opening, which for the purposes of illustrating myinvention, is formed vin a ships plating. vided with a flange @whichextends into the opening, andy lafsecond flange al which is providedwith a screw thread. The flange al is also provided with'a lip a whichwill be referred to later. It is also `provided with' a seat, here shownas being in the form of a gasket G against which acover E Yis levenlyand firmly seated as hereinafter described.` 0 BV designates a-secoifdrino* which is interiorly' screw-threaded and ori-the flange 41,- andlis provided with la' flange b. 'The e ring Bis here shownY asv beingprovided'with State of New York, have invented certain point out thenovel features thereof in As here shown, the ring is pro-V which theshaft C extends. The cover E is also provided with an ear e5, carrying apin c6 which extends into an opening Z provided in the worm D, theopening d being of such length that the pin e6 can be moved inwards andoutwards a short distance. It will be observed that when the worm D isrotated on the shaft C, it will cause the cover E to rotate withitvthrough the pin e6, the shaft C acting as the center on whichtheicover E rotates.

Rotation of the worm D is caused by the engagement therewith of spiralteeth f formed on or carried by a ring F which is revolved in the casingformed by the two rings A and B. The ring F is revolved by means of thegear teeth f1 formed on or carried by the ring F which are engaged by aspur gear f2, mounted on a shaft f3, which also carries an operatinghandle f4. The ring F is also provided with a series of wedging surfacesf5 which co-act with a like number of wedging surfaces c7 carried by thecover E, and which are beneath the wedging surfaces f5. The ring F ishere shown as bein confined in the ring B by means of the flange b andthe lip a2 which fits in a shouldered recess f formed in the ring F. Bythis arrangement the ring is not only confined to its seat, butdistortion of its shape is prevented, thereby insuring correct gearingengagements with the gear f2 and worm D.

l Referring to Fig. 1 which shows the cover in its closed position, byturning the handle f4, the ring F is revolved in its casing, and thefirst part of its movement causes the wedging vsurfaces f5 and e? to bedisengaged. The continued movement of the ring causes the teeth f toengage the worm D to rotate it onthe shaft C, and when it rotates itcarries the cover yE'with it to thereby uncoverl the -f opening. Areverse rotation 'of the handle f4 causes the rotation of the cover E`inthe reverse direction to close the opening, and after the cover hasreached its closed position on the gasket G, the teeth f are disengagedfrom the worm D. The further rotation ofthe ring F causes its wedgingsurfaces to engage the wedging surfaces e7,l which co-act to press theframe e evenly and firmly against the'gasket G, irrespective of the wearof the gasket to make a water-tight joint.V This vinward movement of thecover E is permitted because of the elongated openings in its ears e2,cf and the lengthened opening (l into which the pin e6 extends.

In the event that the cover E for the opening should remain closed for aconsiderable period, it may be that the edge of the cover engaging thegasket G will stick tast to the gl slet, and require some force to breakitloose. To overcome this, I provide a lug o1' projection /t on theframe c (see Figs. l and a) which is engaged by a bevel edge k1, whichas here shown, is formed on one of the wedges or it may be a separateprojection. During the operation ot the pinion f2 'to open the cover,when the wedging surfaces f5 and el are about to be or are disengaged,the edge 71,1 engages the lug or projection to torce or lift the frame cout of engagement with the gasket Gr. The continued operation of thepinion f2 raises the cover as above described.

Having thus described my invention, what I claim as new is:

l. The combination with a casing for an opening; a cover for coveringand uncovering the opening; a pivotal connection between the casing andcover; a ring having gear teeth for moving the cover on the pivotalconnection; a shouldered recess on said ring; and a lip fitting in saidrecess to prevent its distortion when moving the cover on its pivotalconnection.

2. The combination with a casing for an opening; a cover for coveringand uncovering the opening; a pivotal connection between the cover andcasing; means for moving the cover on its pivotal connection comprisinga ring having gear teeth; a shouldered recess on said ring; and a lipcarried by the casing for fitting in said recess.

3. The combination with a casing for an opening, said casing carrying alip; a cover for covering and uncovering the opening; a pivotalconnection between the cover and casing; means for moving the cover onits pivotal connection comprising a ring having gear teeth; a shoulderedrecess on said ring; and a second ring for holding the gear ring inengagement with the lip.

4. In combination, a casing provided with an opening and with a seat, acover for said opening, a member mounted `to oscillate, means controlledby oscillation of said member for moving said cover into and out ofclosing position against its seat, and means also controlled by movementof said member in the opening direction for separating the cover fromthe seat.

5. In combination, a casing provided with an opening and with a seat, acover for said opening, a member mounted to oscillate, means controlledby oscillation ot' said member for moving said cover int-o and out ofclosing position against its seat, a lug iXed -to the cover, and ashoulder fixed to said member and coacting with said lug to separate thecover from its seat during movement of the member in opening direction.
